WALTERLORD AND WILL LORD, OF TODMORDEN, COUNTY OF YORK, ENGLAND.

OPENING AND SCUTCHING MACHINE.

SPECIFICATION forming part of Letters Patent No. 373,899, dated November 29, 1887. Application filed December 17, 1886. Serial No. 52211889. (No model.) Patented in England April 7, 1885, No. 4.221.

ifo aZZ whom it may concern:

Be it known that we, WALTER LORD and WILL LORD, both subjects of the Queen of Great Britain, residing at Todmorden, in the county of York, England, have invented a certain new and useful Improvement in Opening and Scutching Machines, (for which we have obtained a patent in Great Britain, No. 4,221, dated April 7, 1885,) of which the following is a specification.

' Our invention relates to those preparing or opening and soutching machines inwhich one feed roller is employed with a number of weighted pedal-levers fulcrumed near the said roller. The back ends of these pedal-levers are hooked, and on each one is suspended a flat rod or pendant, the lower ends of which rods are made with taper sides, or wedgeshaped, and pass through along box. Between each of these rods or pendants is ordinarily fitted a small bowl or roller loose in the box. When the front end of a pedal-lever is depressed by a hard lump of fiber, the back end raises its pendant, the wedge-shaped portion of which, as it'rises, moves the other pendants sidewise, thereby operating levers connected to the strap-fork guide-lever, which moves the belt on the driving-cones, and so drives the feed-roller at a slower speed.v

Now, our improvement consists, essentially, 1n balancing the strap-fork guide lever or levers by a counter-weight or otherwise, in such manner that the pendants are free to act immediately uponthe cone-belt without having first to overcome the weight of the said lever or levers, and thus the belt-shifting mechanism is made more sensitive.

In combination with the foregoing, and to diminish friction, we also propose to use two or more anti-friction bowls or rollers between each pair of pendants in place of one bowl, as at present customary.

Figure 1 is a side elevation of a portion of a preparing or opening machine-sometimes called a lapping-machine to which ourinvention is applied. Fig. 2 is a plan, part of the casing being broken out, and Fig. 3 is an end elevation of the same. Fig. 4 is a plan, and Fig. 5 an elevation, of our new or im- 'e andf, and strap 9 from the shaft h.

proved compound balance-lever for transmit ting motion to the regulating-cones strap-shifting mechanism.

a represents the frame of the machine; 12, the feed-roller, to which motion is communicated by the worm-wheel a, worm d, regulating-cones The strap that transmits motion from the cone 6 to the cone fi's indicated by a dotted line, z, on Fig. 2.

j is a shaft on which are fulcrumed the the pedal-levers k, the short arms of which coincide at the end with the under surface of the feed-roller b and form the feeding-trough. Thelong armsof the pedal-levers 7c are hooked, and on them are hung the rods or pendants Z, having wedge-shaped ends which pass through a slotted box or frame, at. In this box m, between each pair of pendants, are placed two or more bowls or anti-friction rollers, n, (see Fig. 3,) instead of a single roller between two pendants, which is the ordinary arrangement. The additional anti-friction-roller or rollers between each pair of pendants facilitates the movement of the pendants Zwhen they are raised or lowered by the action of the pedallevers k. A set-screw, 0, enters one end of the box at and bears against a roller, to prevent any movement of the pendants in that direction. In the pendant Z, at the other end of the box, is a slot, p, which receives an adjustable stud, q, which carries one end of the link 1-, which is made in two pieces, one of which is slotted toreceive a bolt, 9, which secures the two pieces together. The other end of the link 1" is connected in a similar manner by a stud, q, to the vertical arm sof the compound balance-lever s 8' 8 This lever, which is shown detached in Figs. 4 and 5, is fulcrumed on an adjustable stud, t, bolted to the slotted bracket n, fixed to the frame a of the machine, and it has one arm, 8', formed in two parts, slotted for longitudinal adjustment and secured together by a bolt, 8. This arm 8 is forked at one end, in which rests one of the cone-strap guide-levers c, which operate the guides x :10, through which the cone-strapi passes.

s is the weighted arm of the compound balanee-lever, and s is the adjustable weight, fixed in such a position thereon as to balance the weight of the cone-strap guide-levers v r.

w w are studs on which are fulcrumed, respectively, the cone-strap guide-levers U 1;. These levers are provided with toothed segments 1;" t)", which gear into each other and cause the levers and the strap-guides :0 ac to move simultamzously in the same direction when acted upon, as hereinafter described, by the arm 8 of the compound balance-lever.

The operation is as follows: If more than the desired quantity of fiber, or if a hard lump of fiber, enter between the feed-roller Z) and feeding-trough formed by the pedal-levers 7. and the front end of a pedal lever or levers is depressed, the long arms of these levers, and by them their pendants Z, are raised, and the wedge-shaped portion of these pendants being drawn upward between the rollers 12, they swing or move the remaining pendants in the direction indicated by the arrow on Fig. 3. The slotted pendant Z, being connected by the link r to the vertical arm 5 of the compound balance-lever, causes the said arm to swing in the same direction, thus depressi ng the weight ed end 8 and raising the forked end of the arm 8' of the compound balance-lever, thereb si multaneously lifting the guide ends of the levers v 0', and by means of the guidesncno' moving the cone-strap 1' up onto the smaller diameter of the driving-cone e and onto the larger diameter of the driven cone f, thus reducing the speed of the feed-roller Z and equalizing the amountof fiber fed into the machine in a given time. \Vhcn less than the desired quantity of fiber is between the feed-roller and feedingtrough, the action of the levers is reversed and the speed of the feed-roller increased.

It is obvious that, the strap-fork guides and guide-levers and their connections being balanced by the weight 8, as shown and described, the belt-shifting mechanism is thereby made much more sensitive, as the pedal-levers 7c are free to raise or lower their pendants l, as re quired, without having first to overcome the weight of the guides and connecting-levers.

What we claim as our invention, and desire to secure by Letters Patent of the United States, is-

1. The combination, with the cone-strap guides and guide-levers, of the compound balance-lever fulcru med on a bracket secured to the frame, the weight s, the link 1', the pendants, and the pedal-levers, substantially as herein set forth, for the purposes specified.

2. The combination, with the conestrap guides and guide-levers, the compound balance-levers, the weight 8, the link 1, pedall'evers, and the pendants, of two or more antifriction rollers, it, placed between each pair of pendants, substantially as and for the purposes specified.

The foregoing specification of our improvement in preparing or opening and scutching machines signed by us this 3d day of December, 1886.
